PATENT f.-'oFF1'c"E` NEW Yonx, nssreNoEoE ONE-HALE To COLONIAL MOTOR COACH ('OIRPOlRA'JJION, OF WATEBTOWN, NEW YORK, A. CORPVO- NATION OF NEW YORK PROTECTIVE DEvIoE Eon vEnrcLE wmnows Application led December 10, 1,927. Serial No. 239.-,153.'

This invention relatesv to a new and im proved protective device for vehicle windows and is particularly desi ned for use on the glass front of an inclose automobile.

When inclosedautomobiles are driven vin cold weather the interior of the vehicle becomes considerably warmer than the outside temperature with the result that moisture will be deposited on the. inside of the windows of the y.vehiclea'nd will freeze thereon which will tend to make the glass translucent instead of transparent with the result that the vision of the driver is impaired.

The main ob'ect of my invention is to provide a device w ich will keep the windows of an inclosed vehicle from frosting no matter what the outside temperature may be com;- f pared with the temperature inside of the vehicle. v l Another object of my invention is to rovide a protective means for the glass windlbws of a vehicle which can be applied and removed with the minimum lof effort.v This is desirable because such a rotective device is not necessary or desirable 1n warm weather. Other objects an'dadvantages relate to the size, shape and arrangement of parts,'as will more fully appear from the following description, taken in connection with the accompanying drawings in which AFigure 1 is a perspective view of my deise applied to the Windshield of an automo- Figure 2 is a section on line 2--2 of Figure rFilgure 3 is a' section on line 3-3 of Figure Figure 4 is an elevation of a modified form of my device. 0 Fi4gure 5 is a section on line 5-5 of Figure - the driver it will be understood `that the frame can bey made of the proper size and vshape to cover the full winds ield, if desired. Similarl although I have shown the application o my device to the windshield of'an automobile, other devices, of the' same lnd and character can .be applied to the other windows of the vehicle. A

The device is preferably installed on the inside of the glass front and is placed against Athe outer' rim of the front with a filling means -4- such as felt around the device and between it and the glass of the glass front.

tion are preferably adjustable so that they f i may be from time to time taken u to insure that the device is always in tig t contact with the windshield frame. I have here shown six retaining devices ,5- although it will be understood that the number and position of such retaining devices will be etermined by the size and shape of the frame -1-.

The retaining -devices are similar and, therefore, a description of one will be adescription of all. The retaining device 5 consists of a U-shaped body -6- which is fastened to the bc-ly of the automobile -7- adjacent to the frame `-8- of the glass front by screws -9.-'or other convenient means. The body 6 is pierced by threaded h'oles so that the take-up screw lO- when -12-,. The forward end of the screw l0- carries a cushion elB-q preferably of rubber, so that the screw -10- will not be directly affected by the vibration of my device.

are threaded forwardly through the body 6- with the knob l3- against` the frame -1- of my device that the device will be forced forwardly against the cushioning strip -4- which, in turn, will be forced againstthe glass -14- ofthe glass front of the vehicle. vWhen the device is'thus in position' af dead air space --15- will be formed between the glass #-2- of my device and the glass -14 of the glass front.

' It is well-known that a dead air space is a very eiiicient insulating means and the result in this case is that the glassl of my. device will not become suiciently cold to cause moisture from the air inside the vehicle 'to be deposited on' it. For the same reason the air` in the dead air space 15 will not become sufficiently warm so that moisture will be deposited on the inside of the glass --11-v .of the glass front. The result of this is that -10- are all retracted vthat my device may be easily removed from .its position when it is not desired to'have it in place.

In Figures Lland 5 I show a modified form of my device in which I attach it to the windshield of an automobile by means of s ring clips l5 and 16 which are similar in esign and a description of one is a description of the other. f

Spring clip -15-. consists of a narrow curved fiat spring -17 which is 'secured to the top 18- of the wind-shield Vframe by means of screws -19-. The .lower end .-20- of spring -17- is returned bent to form a clip for the reception of the glass -2- 'of my device. 'In thisl modified form the frame -l previously described is omitted and the glass -2- without a frame .-1- is positioned against the wind-shield. 1A take up screw`2l is secured to the top 18 of the windshield frame by-means of screws Q2- and is positioned below screws 19-. Take up screw -21- extends through a hole in spring -17- and carries on its outer end a wing nut ,-f23-. When spring -17- is in position on frame 18- and is not under tension its shape is such And although I have shown and described j a particular form, size and arrangement of parts as illustrative of an embodiment of my invention Iv do notv desire to restrict myself .to the exact shape, form or relation of parts,

as various ichanges may be made within the scope-of the appended claims.

What I claim is 1. A protective devicefor vehicle windows comprising a glass smallerin size than the window to be protected, a filling means on the edges otone side of the glass, a pair of springs having their upper ends positioned above the window and having their lower ends return bent for the-reception of the lower edge of the glass, a finger mounted on each of the springs for registration with the upper edge of the glass, and means for increasing the tension on the spring whereby the glass is held against the window with the' filler therebetween.

2. A protective devicefor vehicle windows comprising .a glass smaller in size than the window to be protected, a filling means on vthe edges of one side of the glass, a pair of springs having their upper ends positioned above the window and 4having their lower ends return bent for the reception of the lower edge of the glass, a linger mounted on each of the springs for registration with the upper edge of the glass, bolts positioned above the window and extending through holes in the springs2 and nuts on the bolts for moving the springs .toward the window.

3. In a device of the `class described, a glass a cushioningdevice on the outside edges of the glass on one side thereof and spring means for. holding the cushioning device and thel glass against the inside of avehicle window to make an air-tight joint, said spring means constituting the sole support for the glass.

In witness whereof I have hereunto set'my hand this 26th day of November, 1927.

that its lower end -20- will be adjacent to the glass -14- of the wind-shield. It will be understood that when wing nut-23- is screwed down against spring -17- it. will cause spring -17. to exert a spring pressure j .at its lower end against, glass-14- and this pressure may be increased or decreased as desired by screwlng wing nut 23Y towards or :from spring `17-. In a position to register with the upper en Q4- of glass 2 s ring --17-l carries an .inwardly extending nger 5 25- of asize and shape to-exert on the top part of 24. a pressure approximately equal to the pressure exerted on the lower' end of glass 2P by the lower-end QO- of spring --1"1'-'.`
